From the smallest fly to the blue whale, from a blade of grass to a towering redwood, everything exploits the natural resources that Earth and its other inhabitants provide. In order to ensure its survival, an organism must assimilate itself into the food web or risk extinction at the hand of natural selection. Sometimes, a species is accidentally or purposefully introduced into a new area. These newcomers, commonly known as invasive species have no choice but to make themselves a part of the food web or die out. Unfortunately, that usually leads to fierce competition for resources between a local species and the invasive one, in which only the victor is allowed to survive. In a relatively short amount of time, the sudden pressure on resources can completely upset and destroy an ecosystem, taking the invasive species with it. With the invasive species destroyed, the ecosystem can slowly rebuild back to the way it was before. According to National Geographic, an invasive species is a “type of plant or animal that is not indigenous to a particular area and causes economic or environmental harm.” (National Geographic). Based on that definition, humans sound suspiciously like an invasive species, except on a global scale. If humanity does not decide to become more sustainable soon, we will suffer the same fate as other invasive species: extinction. Luckily, the pressures of human exploitation of the environment for resources can be mostly eliminated through the use of
“Hey guys! This is the last communication you shall receive from me. I now walk out to live amongst the wild. Take care, it was great knowing you” (Qtd. In Krakauer 69). After graduating from Emory University, Christopher McCandless abandoned everything, gave his entire savings account to charity, and then hitchhiked to Alaska to live in the wild. In the novel, Into the Wild, Was McCandless justified in shunning society? McCandless was justified in shunning society because he simply wanted to find himself and be independent without any distractions from his friends or family.
By taking action, people will eliminate the problem in a shorter, more effective manor. One article states, “Since people can now travel around the world much more easily than they ever could before, it has become easier to introduce invasive species by accident,” (Alien Attack, paragraph 5). This demonstrates how quickly species can spread with the help of humans. People need to eliminate these species faster in order to save ecosystems. Overall, humans need to remove all invasive species before they take over the ecosystems of the world.
It is often noted that one can never truly understand the beauty of life until they go and experience it. This idea parallels with getting to know who they really are and figuring out what their purpose in life genuinely is, which not many people cannot comprehend. Everyone has different fears, desires, and feelings, but not until you live a life of new experiences do you harness your true self. Growing through experiences and connecting with nature allows someone to more deeply reflect on their individual purpose on Earth and discover their own definition of happiness. Henry David Thoreau comments on this even further by proposing that the disconnection from a society in which we are comfortable is the only way to cultivate an understanding of ourselves. Chris McCandless sets out on an adventure in a life absent of routine to push his boundaries and prove that he could make it on his own, finding the meaning of life in the process. Henry David Thoreau’s statement “Not until we are lost do we begin to understand ourselves”, is correct, as evidenced by Jon Krakauer’s novel Into the Wild.
Into the Wild is a novel about Chris McCandless who left everything, and everyone he knew after college and essentially disappeared into the wild. A commonly asked question at the end of Into The wild is why did Chris McCandless do this, why did he abandon his college education and everyone he knew. Many have tried to figure out just this question but with the help of the memoir Walden, a book that heavily inspired McCandless, it is easy to see why McCandless left his conventional life. These reasons are that He wanted to be more like nature, to go with the flow and not let every little thing throw him off, Chris took this to the extreme and literally joined nature to get a better understand of it. He also wanted to live a simpler life, Chris again took this to the extreme by leaving everything that was extra or unneeded in his life. The final reason is that he wanted to see what reality and real life must offer, he didn’t want to see and live with the reality that other people imposed on things.
An invasive species is a species that comes out of its natural environment, and enters another. These animals are usually very bad for the ecosystem and may cause an unbalance. These animals usually come in with many competitive advantages and can easily dominate any competition. This will give them the ability to eat as much as they would like without being threatened in any way. This could possibly diminish many populations and end an entire ecosystem.
Understanding oneself is one of the most important factors in living a free life, and living on the road can be a big part of this process. In the novel, Into The Wild, Jon Krakauer writes about a boy who ventures into the wilderness and inevitably learns more about himself on a journey right before he dies. In order to avoid his problematic family, Chris McCandless journeys into danger where he meets people who help him learn more about the world. Although he does eventually meet his end in Alaska, he leaves the world without worries or regrets. By living on the road and in nature, Mccandless is able to live the life that he wants and be free from the clutches of society. While living on the road can prove fatal, it allows a person to find themselves and avoid the problems of society; therefore, people should look to nature in order to better understand themselves.
For someone to be on the road, people usually assume that they have lost hope in life, or that they were not that determine to maintain a place in our social class.Those who decided to live on the road do it for a different reason, reason that are either a push or pull factor. Someone who has helicopter parents, or having a difficult time trying to fit into society can find a reason to venture out and find self. Someone who felt like they no longer have a purpose in life, can find it by going on the road, because no one know you better than yourself. When writing a story of your life, do not let anyone else hold the pen. Just like the north star, which helped slaves find their way from slavery and captivity. In order to find true self, risk must be taken. While life on the road can seem like an act of avoidance of reality and problems, it can help someone find a purpose for life and their true self, therefore I believe that life on the road, is helpfully for those who are struggling with problems.
Influence on ecosystems range from human causes like the bulldozing of a forest to natural causes like a fire or a flood. In recent times, the introduction and spread of invasive species has transformed native communities rapidly and, in some cases, created irreversible damages. In the Earth’s history, changes have often occurred in the ecosystems. For example, glaciers and the retreat of glaciers cause wide-spread changes. However, although change is a constant in ecosystems, animals and habitats often cannot adapt to the rapid alterations of non-natural stresses. Harm to the environment from the introduction of invasive species occurs through changes in the habitat and declines in the native species. Invasive species
The biodiversity effects of non-native invasive species have been described as “immense, insidious and usually irreversible” (Veitch and Clout, 2002). There is significant evidence proving that invasive species can cause severe economic, environmental and ecological damage (Mack et al., 2000). A lot of time and research has been devoted to dividing the world into regions with distinctive habitats and species. Numerous pathways, mostly anthropogenic, are breaking down these realms and facilitating the ecological and biological invasion of non-native species.
Exotic animals should be banned from being purchased, hunted, and or traded from their natural habitat. People can look at an exotic animal for a couple minutes, but captivity affects their whole life. Exotic animals caged in non-natural habitats can experience many physical, and mental issues.
One specific way that humans have begun the process of world extinction is through their incessant meddling with the environment. Not only do people destroy the environment with our wreckage and pollution, but the human race has introduced species into other ecosystems, causing massive repercussions. Referred to as invasive species, their introduction into a
Invasive species are organisms that are not native to an ecosystem and cause harm to it. These organisms are capable of bringing about a great deal of damage to the ecosystems they are foreign to. This can range from disrupting the growth of the environment it has taken over to completely decimating other species. The introduction of invasive species to new environments often involves humans. The way that invasive species are introduced to a new environment varies greatly. Invasive species may be introduced by something as simple as humans accidentally tracking species into a new environment from the bottom of their shoes, or something bigger like destroying an ecosystem to clear the land, forcing the species that lived there to flee to a new ecosystem that can be disrupted by the presence of a new species.
Despite what mankind would like to believe, humans are animals. As multi-celled organisms, we consume other organic matter, change the land for own uses as a beaver would build a dam, and as other mammals, we are all fed breast milk from our mothers when we were young. Yet there is this disconnection and alienation of the human race towards other species. Moreover, through fear of taking action, the convenience provided to us if we simply choose to ignore the environment, and the alienation of other species that are endangered by our actions, the hostile and uncaring attitude of humans towards nature is the core reason for many of the problems in our environment today.
The places we visit throughout our lives can sometimes leave a bigger imprint on us than anything else. The novel, Into The Wild, by Jon Krakauer, displays a man, named Chris McCandless, who selfishly goes into the Alaskan Interior alone. The places he visits and the way he connects with the people and places around him before and during the journey help exemplify who he is.
With nearly millions of animals dying each year from being captive, or endangered species being hunted down and killed, we need to discover a new way of displaying that our world is full of beautiful animals and wildlife. Wild animals are suffering both physically and mentally from the lack of freedom that confinement imposes. These harmful environments are preventing animals from having the opportunity to live in, and be exposed to their natural habitats. Keeping animals imprisoned in cages and small enclosures just for the sake of human observation causes stress and frustration, which is risking animals overall health and well being. These morally unacceptable and cruel actions of retaining wild animals in captivity is certainly wrong.
